I have made almost all the 9-patch squares (11 more to go!) this weekend.
Pic above is a few of the purple, plum, lilac and brown blocks just to see the colors together, I am making the primarily green & brown mixed ones tonight.
I plan to decide if I want all one color filler of solid Brown or light green or if I'll use scrappy fillers of all colors, OR if I have a wash of dark to light colors. I will try out variations and if I remember to take pics I will post them.
